This article surveys three "examples of the use of knowledge structures in intelligent systems for workplace learning," (APOSDLE, MATURE and Learning Layers) and describes the development of such tools as domain, task and competency models, among others. The paper describes forward progress but acknowledges "we are still far from understanding how knowledge services that operate on emergent knowledge structures contribute to individual learning." I think that the author projects a lot more unity than there actually exists in the field. "It now appears much more realistic than 10 years ago to conceive of intelligent AI solutions that consider human activity as a social and situated practice around shared artefacts that can be traced and supported in technologyâ€enhanced workplace environments." I think that a lot of stuff has been done, but am unable to say that we can measure any specific progress toward the eventual outcome.
